We understand the critical nature of your requirements.

The coatings required by the medical industry are of the most critical supplied by the coating industry today. The nature of PVD coatings being applied in a clean, vacuum environment with improved adhesion compared to wet bath platings, provide you with a higher-quality surface coating that will be durable and improve the appearance, wear and corrosion-resistance of your instruments.

Surgeons are among the most highly educated professionals in our society. Providing them with the highest quality instruments, the most advanced designs, the best steel possible and the most advanced surface treatments to enhance the instruments performance is what they expect. NCT can help you provide the highest quality, most dependable, innovative surface treatments available in today’s market. Whether you would like to improve your instrument’s corrosion resistance, reduce wear of moving parts, or use a coating for identification purposes, NCT can provide you with the surface treatment you require.

Our automated processing equipment will ensure you a consistent coating is deposited onto your instruments each and every time they are coated.

High quality, consistent uniform coatings are what you require and expect. Crisp lines of demarcation and an even gold-tone appearance provide your customers with the highest quality, most professional looking instruments in the marketplace today.

The coating can be applied at temperatures that will not affect your instrument’s core hardness or metallurgical structure.

CrN (Chromium Nitride)
- SHOW -- HIDE -

A chromium based coating that will protect your instruments from corrosion and abrasive wear. The PVD coating process will deposit a coating that will replicate the surface finish present when the coating is deposited. The uniform silver appearance of the coating is sometimes desirable when instrument manufacturers prefer to use a coating that is similar to the instruments steel appearance. Masking of non-required surfaces is possible and the CrN will survive autoclaving.

TiN (Titanium Nitride)
- SHOW -- HIDE -

A medical grade titanium nitride coating that is uniform in appearance and will replicate the surface finish of the instrument. The titanium nitride will improve your instrument’s corrosion resistance as well as provide an aesthetically pleasing product that has the rich gold-tone appearance and the durability of a coating used daily in demanding industrial applications. This coating is also used as a visual reference for certain instrument category, design or size identifier. Non-required surfaces can be masked to prevent the coating from being deposited in those areas. Our titanium nitride has survived thousands of ours of autoclave testing with no degradation in film quality.

AlTiN (Aluminum Titanium Nitride)
- SHOW -- HIDE -

AlTiN is a dark charcoal grey/black coating that has a high surface hardness and works well when customers require a nonreflective light absorbing surface. The AlTiN will provide you with a uniform black surface coating that exhibits all of the benefits of the other PVD coatings. AlTiN can be deposited at low processing temperatures and masking of non-required surfaces is possible. AlTiN can be autoclaved without degradation of the coatings appearance.

ZrN (Zirconium Nitride)
- SHOW -- HIDE -

ZrN exhibits a light gold appearance with a surface hardness slightly higher than titanium nitride. ZrN will provide good abrasion resistance and superior performance when in contact with non-ferrous components. ZrN has a higher density than Tin as well and will provide superior corrosion protection. ZrN is deposited at low processing temperatures using the PVD coating process. Masking of non-required surfaces is possible. ZrN can be autoclaved without degradation of the coating’s appearance.
